CVE-2026-64154

In the Linux kernel, the following vulnerability has been resolved: drm/msm/adreno: Fix a reference leak in a6xxgpuinit In a6xxgpuinit, node is obtained via ofparsephandle. While there was a manual ofnodeput at the end of the common path, several early error returns would bypass this call,...

CVE-2026-64154

The flaw is in the Linux kernel's Adreno GPU driver (a6xx_gpu_init), where of_parse_phandle() acquires a device node reference that early error returns fail to release via of_node_put(), causing resource accumulation. The fix uses __free(device_node) for automatic cleanup. Red Hat notes it is not...

CVE-2026-64147

In the Linux kernel, the following vulnerability has been resolved: pdscore: fix debugfslookup dentry leak and error handling debugfslookup returns a dentry with an elevated reference count that must be released with dput. The current code discards the returned dentry without calling dput, causin...

CVE-2026-64147

The pds_core kernel driver leaks a dentry reference (missing dput()) on every firmware reset recovery, and when CONFIG_DEBUG_FS is disabled, debugfs_lookup() returns ERR_PTR(-ENODEV) rather than NULL, which the existing check passes, causing a crash. Red Hat confirms this can lead to denial of se...
